Familiarity: I've put it through the wringer
Fit: True to size
I have solution, hornet, black wings, G2 predator for aggressive shoes, and this one is by far my favorite. Snug fit, i wear size 8.5 in these, and 9 street shoes, super tight, but surprisingly very comfortable, the only set back is the heel doesn't fit me too well and i have an air pocket, but no 5.10 heels ever fit me well.
Rubber is supper soft and sensitive, so soft that i feel comfortable climbing slab in these (you read that right, slab).
Love the color. definitely works best for over hanging routes, but i wear these for any climb, even multi-pitches. This is the perfect shoes for me, it's the tits.
